SELF-ACTING CHEESE-PRESS.

Specification ofL etters Patent No. 2,739, dated July 28, 1842.

f Stone and Collins Self-Acting Cheese- Press and we do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification.

The nature of our invention consist-s in applying the combined power ofthe screw and joint-lever to pressing cheese.

To enable those skilled in the art to make and use our invention we willproceed to describe its construction and operation.

The machine consists of, first, a form (1.) being a circular piece ofplank say two feet in diameter and one inch and a half thick securedfrom warping by a batten or narrow piece of wood crossing its lowersurface and secured by iron screws in the middle of the lower surface ofthe form, which form is placed horizontal upon four legs say threeinches long each; secondly, two wooden screws (2) (2) one inch and aquarter in diameter and eighteen inches long to the shoulder whichscrews stand upon opposite sides of the form, and perpendicular thereto,being placed over the ends of the batten above mentioned, and having aspace between them of say nineteen inches: each screw having at itslower end a tenon say four inches and a half long which tenon passesthrough the form and end of the batten and is fastened by a key on theunder side of the batten; thirdly, a cross bar or beam (3) being a barof hard wood say two feet long and two inches square having a holethrough each end sufficient to admit the wood screws above mentioned,

which beam is secured and kept firm by four nuts or screw boxes ((Z cl)one above and one below each end of the beam; fourthly, two uprights (4)(4L) or pieces of wood say one inch and a half square, and ten incheslong between the shoulders, having tenons on each end and being groovedon one side with a narrow groove running from shoulder to shoulder.These uprights stand upon the upper side of the beam perpendicularthereto and also to the form; being four inches. apart and equallydistant from the center of the beam: having their lower tenons set intothe beam and being secured at the top by a cross piece or small piece ofwood which receives their upper tenons. Lastly, two levers (5) (5) eachconsisting of three pieces of-wood all one inch and an eighth thick; oneof which pieces (a) (a), is two inches wide, and the other two (5 b) (bb) one inch wide each. These pieces are so joined together that the twonarrow pieces constitute one part of the length of the lever and thewide piece the other part, making a joint (0) near the'middle of eachlever which joints are sustained by a pivot, and which for distinctionwe call the middle joints of the levers. The lower part of each lever istwo inches longer than the upper part or part above themiddle joint; thelower part being twelve inches long and the upper part ten inches. Thelower or longer part of one lever being constituted of two narrow piecesand the lower part of the other of one wide piece. These levers twoinches from the lower ends are connected to the lower side of the beam,with leather strings making the lower side of the beam their fulcrum,and are so attached as to cross each other at the place of their unionwith the lower side of the beam, which lower side of the beam as far asthe levers strike it, is brought nearly to an edge making a pivot onwhich the levers turn in pressing. This union of the levers at thefulcrum or lower side of the beam we call the lower or fulcrum joint (6c) of the levers. From this lower or fulcrum joint, at which their lowerends cross each other as above stated, the levers pass outward from eachother and upward to their middle ing angles or elbows at their middlejoints they pass upward and inward toward each other, until their upperends meet between the uprights and over the beam where they are unitedby a pin or pivot forming a fourth or upper joint in the lever (f f),which upper joint is kept vertical to the lower or fulcrum joint by thetwo ends of its pivot moving in the grooves made in the uprights. Inusing this press, the beam is first raised nearly to the top of the woodscrews. The. curd is then placed upon the form in the cheese is pressedmore or less in proportion to its size.

What We claim as our invention, and desue to secure by Letters Patent,1s-

The application of the power of the screw and joint lever, in a selfacting press, for the purpose of pressing cheese, as herein de-'scribed.
